Easy Nitrous Question

[Danman765432]

Well, it seems like my nitrous kit will be going in very soon due to the fact that my brother finally took it out of his car and i ordered the parts to adapt it over to my car. My question is that am I going to need to get dyno tuned in order to run the nitrous properly?

Right now my car has not been tuned and ever since i put in the 3:73s i have been banging off my rev limiter as is. I am assuming that the nitrous will make it worse even with a window switch. I only plan on doing a 100 shot and the kit says the stock fuel pump can handle up to a 125 shot. I will be buying a fuel pump in the future but not yet.

You really need to get rid of that rev limiter if you are going to spray it. My car had a Superchip in it when I bought it. I've removed it once, and the only big difference I could see was the rev limiter has been removed with it in the car. If you are hitting the limiter now, you will definately hit it on the bottle.

I was really hoping to avoid a tune since i wanted to only do it once when i got my heads and cam put in too

Also what times do you guys believe i could achieve just on the nitrous, once i get tuned and such?... just wondering

Our cars have a rev limiter?

......yes..............

THERE is NO reason to get near the 6,250rpm rev limit with stock or gt40 heads, even some alum. head combos do not make power that high.

A window switch with the proper pills to turn off the bottle at say 5,800 rpm will be plenty good. As with the stock intake your done at 5k, and with a gt40 or like intake and stock or stock gt40 head combo your done by 5,500.

If your an auto...I would get a tune if not for shifts alone, The auto still has no need reving to 6,250 rpm.

The bottle will get the rpms up faster so you just need to pay attention to when to shift and get that down. Not floor it until you hit the rev. limit or redline on the tack.

I guess Ive never revved it that high. I always shift when I feel it losing power. never felt the need to keep pushing it.

don't be cheap...get a tune. don't forget to thank your brother for helping you out. he seems like the coolest dude around. i wish my brother were half as cool...he's a dee dee dee who's car is always broken

Just to let you know the rev limiter in my car since it is an auto seems like it hits it around 5400 to 5500...i dont know if it is different between manuals and autos, but it is totally not going up to 6250 to hit the rev limiter or maybe my tach is to slow for what the computer is reading, which my brother pointed out and also this is when the car is in Drive not me manually shifting it. Ill try to get a video for you guys to see what it actually does..

I have been reading some posts on rev limiters and i have seem with aodes that it is a problem and that they need to be corrected by a chip...in alot of these posts Don talked about get a custom SCT chip to fix the problem, by changing the shift points and when the converter should lock up.

I also found this posted by Paul/Killercanary "Grady is correct, the limiter in the AODE cars is MUCH lower than the the T5 T4MO computer which is set at 7000rpms unlike the T5 A9L coputer found in the california 1988 and all 89-93 fox bodies. I'm fairly positive the 94-95 AODE rev limiter is set at 5250 or 5500... its one of those. As was mentioned you MUST raise the rev limiter with some sort of add on chip, an MSD and the like willl not allow you to raise it, but after its raised they can be used to activate the rev limiter at any rpm LOWER than what you set the chip at."

My car also went from 2:73s to 3:73s...from reading around on many different sites i see banging off the rev limiter is likely and the limiter is around 5500 rpms on and AODE.

Correct. My rev limiter is not ANYWHERE near 6,000+. I really think mine is the 5,250. I only tried it twice that day though, and quickly put the chip back in.

 

[Danman765432]

Ok good I knew I wasnt screwed up in the head, because my tach doesnt even go close to 6k rpms it barely gets to the redline mark so that is good to know.... Just one other thing I am making my set like the nos setup and I was just wondering is 2 solenoids necessary to run just the nitrous? If that is true I need to buy 1 more solenoid for the purge.

 

[Danman765432]

Also is the bypass jet necessary on the vacuum tee going down to the intake manifold? Since I am trying to piece together some of the parts i need to adapt it over to my car.

I guess Ive never revved it that high. I always shift when I feel it losing power. never felt the need to keep pushing it.

that is because you are smart. there are guys on the 05+ forums asking what to raise their stock car's redline tune, and then i become the enemy when i bust out the ol' "why would you do that? what makes you think your car pulls to 6500?"

 

[Danman765432]

bump on the question about the vacuum tee in the NOS kit that has the bypass jet, since i want to know if i can just use a normal vacuum tee?

buy it sucka - i don't feel like trying to weld/epoxy a jet into an autozone vacuum tee
